htonll function

The htonll inline function converts an unsigned __int64 from host to TCP/IP network byte order (which is big-endian).

Syntax

unsigned __int64 htonll(
  unsigned __int64 Value
);

Parameters

Value

A 64-bit unsigned number in host byte order.

Return Value

The htonll function returns the value in TCP/IP's network byte order.

Remarks

The htonll inline function takes a 64-bit number in host byte order and returns a 64-bit number in the network byte order used in TCP/IP networks (the AF_INET or AF_INET6 address family).

The htonll inline function can be used to convert an IPv4 address in host byte order to the IPv4 address in network byte order. This function does not do any checking to determine if the value parameter is a valid IPv4 address.

The htonllinline function does not require that the Winsock DLL has previously been loaded with a successful call to the WSAStartup function.
